President, SoundSide Physical Therapy
Graduated from the University at Buffalo in 1999
Degrees in Physical Therapy and Sport & Exercise Physiology
When I became a physical therapist my goal was to provide outstanding one-on-one care. Not satisfied with the quality of care that was available, I decided to venture out on my own. I began small, visiting homes of my patients to provide the excellent one-on-one service that I believe in. The overwhelming response I received from my home care services led me to open my first clinic in September 2001.
It has been a pleasure being part of the local community which has enabled us to relocate my practice nine years later to a much larger state-of-the-art medical complex located in the heart of Locust Valley. The goal of my outpatient orthopedic facility is to continue the intense one-on-one attention while offering the best environment for rehabilitation. I have invested in new state-of-the-art equipment, including the Biodex un-weighting system and a line of Quantum & Sci-Fit exercise equipment.
As always, my primary goal when treating patients is to provide quality one-on-one physical therapy allowing our patients to progress with rehab in the most timely and efficient manner possible. SoundSide stands for quality care with a personal touch.
